Filter by:The purpose of this study is to observe and preliminary explore the efficacy and safety of combination of Apatinib and SHR-1210 regimen in treating advanced hepatocellular carcinoma or gastric cancer. Apatinib is a small-molecule vascular endothelial growth factors receptor (VEGFR) tyrosine kinase inhibitor, similar to vatalanib (PTK787), but with a binding affinity 10 times that of vatalanib or sorafenib. SHR-1210 is a humanized anti-PD-1 monoclonal antibody.
The purpose of the study is to evaluate the efficacy and safety of S-1 plus Oxaliplatin versus S-1 only as adjuvant chemotherapy after curative distal gastrectomy in patients with locally advanced gastric cancer.
One paraffin block is routinely used for Human Epidermal Growth Factor Receptor 2 (Her2/neu) immunohistochemistry (IHC) assessment. Here, investigators investigated if picking two or multiple paraffin blocks for Her2/neu evaluation is an economical, efficient and practical method, which may reduce false-negativity of Her2/neu IHC assessment due to intratumoral heterogeneity.
Patients with resectable solid primary cancers and even limited number of metastases are potentially curable. However, most patients develop recurrences despite surgery. Circulating and disseminated tumor cell (CTC/DTC) and circulating cell-free (cf) DNA isolation from the blood, urine and bone marrow will increase understanding of cancer spread and advance knowledge to develop individualized therapies.
Helicobater pylori plays an important role in the development of gastric cancer. Eradication therapy can reducing the morbidity of gastric cancer, but can't totally prevent it especially when atrophy and more serious precancerous lesions already happened. Prior studies found the gastric bacterial difference among gastritis, intestinal metaplasia and gastric cancer. However, they didn't reach an agreement. Correa's model is widely accepted in the development of gastric cancer. The pathological change makes a more suitable environment for bacteria to overgrowth. This study are designed to analyze the gastric microbial difference of non-atrophic gastritis, atrophic gastritis, intestinal metaplasia, intraepithelial neoplasia and gastric cancer.
This study is designed to compare the three chemotherapy regimens(TEGAFOX Sequential S-1 or SOX Sequential S-1 or SOX non-Sequential S-1) for postoperative patients with gastric cancer, observe and record the efficacy and tolerance,to evaluate which regimen is better.
As the number of obesity continues to increase, surgical oncologist pay more attention to the effect of obesity on surgical outcomes and survival of digestive systemin cancers. Body mass index(BMI) is one of the most widely used measurements of obesity. Abdominal fat area (AFA) calculated by computed tomography is popular because of its validity of fat distribution. There is still no consensus which of BMI and AFA could be the more effective measurement and more accurate to evaluate effect of obesity on surgical outcomes and survival. Gastric cancer is one of the most common digestive system cancers, and gastrectomy is the primary therapeutic options.It is important to compare the different measurements(BMI or AFA) to assess obesity and effect on surgical outcome and survival for gastric cancer patients.
Selection of the optimal treatment for gastric outlet obstruction in patients with radically unresectable gastric cancer remains controversial because previous studies comparing the two procedures had a small sample size as well as they included various etiologies such as gastrointestinal (GI) cancer, duodenal cancer and pancreaticobiliary cancer in selecting the patient population. Therefore, to establish the standard of care for patients with radically unresectable gastric cancer with gastric outlet obstruction, a larger prospective, randomized, controlled clinical trial using a single type of stent is warranted.
Perioperative chemotherapy is the gold standard treatment in the resectable and advanced gastroesophageal adenocarcinoma. The efficacy of this strategy has been demonstrated in two randomized studies (1,2). It reduces tumour size before surgery, treats micrometastases and evaluates chemosensitivity. Disease free and overall survival rates were significantly improved with perioperative chemotherapy compared to surgery alone. However, the limitation of these studies is that among all patients requiring chemotherapy, almost 70% of patients will not have the complete sequence. This sequence is defined by the administration of 2 to 4 cycles before and 2 to 4 cycles after the surgery, according to the protocol. The major cause of absence or impossibility of realization of postoperative chemotherapy was the presence of postoperative complication, postoperative serious asthenia and impaired nutritional and physical status (1,2). Poor physical condition assessed by cardiopulmonary exercise testing, reflecting a reduced physiological reserve, is predictive of postoperative complications (3,4). A physical training, even during a short period and on a various population, is beneficial in improving physical condition, cardiopulmonary function and muscular mass of the patient (5-8). A prehabilitation over a 6 week period between surgical consultation and surgery decreases postoperative morbidity and the hospital stay in cardiovascular surgery but no study has ever been performed in the gastric or oesophageal cancer (7,9). Prehabilitation revolves around three axes: 1) a physical training based on initial cardiopulmonary exercise testing (VO2peak, anaerobic threshold (AT) and 6-min walk test (6MWT)), 3 times by week, supervised by a physical therapist 2) a nutritional care to ensure the compliance of the nutrition program and adapt the nutritional management based on protein and energy needs and on the level of spontaneous oral intake and 2) a psychological treatment by a psychologist to reduce preoperative anxiety. To our knowledge, no study ever focused on the gastroesophageal cancer. The benefit of prehabilitation in this cancer may be particularly important because 1) this surgery is associated with a high postoperative morbidity (40%, especially respiratory) and mortality (5%) 2) the physical and nutritional status of these patients is often precarious (cancer cachexia, gastroesophageal obstruction), and 3) the need to preoperative chemotherapy declines physical reserves and is associated with a lengthening of the time between consultation and surgery of more than 3 months (10). Also, the investigators hypothesize that with a physical training, a personalized nutritional support and a psychologist management may decrease postoperative complications, increase postoperative nutritional status and so, would allow for more patients to receive their full cancer treatment. The aim of this study was to evaluate, in gastroesophageal adenocarcinoma, the effect of prehabilitation compared to conventional care, the percentage of patients reaching the complete oncological treatment decided in a multidisciplinary tumour board.
The main purpose of this study is to evaluate whether the Apatinib can improve the disease free survival (DFS) of gastric cancer patients in stage IIIB/IIIc, who had completed postoprative adjuvant chemotherapy. Meanwhile, the investigators also will evaluate whether the Apatinib can improve the overall survival (OS), estimate the quality of life of patients have taken the Apatinib and monitor the security of Apatinib.
